Nami is a fictional character in the One Piece franchise created by Eiichiro Oda. She is based on Ann and Silk, two characters from Oda's previous manga Romance Dawn. She is introduced as a thief and pickpocket who possesses skills to tell the climate and draw sea charts. At first, she is a subordinate of the fishman Arlong, but she is eventually freed of this service and permanently joins Monkey D. Luffy for her dream to write the complete map of the Grand Line. She is the first main character to appear in the anime series.
In the series, Nami is the Straw Hat Pirates' navigator, who dreams of drawing a map of the entire world. Despite her initial distrust of pirates, Nami eventually changes her mind after being around Luffy and the rest of the crew. Nami is depicted as an intelligent girl who has an obsession of obtaining money. She is able to use her three-sectioned staff and use her climate skills to create powerful attacks; the most prominent of these staff weapons is the Clima-Tact, in which she manipulates the climate to create weather-based attacks.
